UNITED STATES PATaNT OFFICE NATHANIEL A. BOYNTON, OF NEW YORK, N. Y.

||v| PRovEM ENT IN. COOKING-Noves.

Specification forming part of Letters Patent'No'. 86,4939, dated February 2, 1869.

To all whom it may concern:

Be it known that I, NATHANIEL A. BovN- TON, of the city ot New York, and State of New York, have invented certain new and useful Improvements in GookingStoves 5 and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon, in which drawing- Figure l represents a vertical section of my improved stove in the plane x x in Fig. 2. Fig. 2 represents a vertical section in the plane y y in Fig. 1. Fig. 3 is a view of the exterior of the door E and of the tailpiece. Fig. 4 is an inside view of the door, with the taiLpiece.

This invention relates to cooking-stoves 5 and consists in several features of improvement, as hereinafter described, and as shown in the drawing.

The letter A designates the stove, which may be made of any desired proportions or shape, provided the principle of my improved construction and arrangement is adhered to.

The top of the stove is provided with boilerholes, which can be conveniently arranged without crowding, because the eXit-ilue is made to leave the stove at its side instead of at its top. i

The letter B designates the fire-chamber, whose grate C is revolved in the usual 'inanner by a wrench applied to the end of one of its journals.

Below the level of the grate C is an opening or pokehole, D, in the wall of the lire-chamber, the object of which is to allowa poker to be inserted below the grate, to clear it of ashes and cinders by that means. l

The opening D is closed bya balancingdoor, E, which is seen in edge view in Fig. 2 and in front view or elevation in Fig. 3, and which is so constructed and arranged as to remain either open or closed by gravity without requiring any fastening, said door being made with a tail-piece, F, which is received within the stove, where it swings or vibrates up and down when the door is opened and closed.

The tail-piece F is connected to the door by a horizontal plate, G, which is concave on its under surface, and forms ashoulder that rests on the bottom edge of the opening D and allows the door to turn on such edge, the said plate G being made of such a length as 'to lit easily between the sides of the opening; but that part of the door which remains on the outside of the stove is wider and longer than the opening D, andlits edges consequently overlap the sides and vtop of the opening. The tail-piece is also made wider than the opening. This greater width of both the door and tail-piece, as compared with the width of the opening D, prevents the door from falling out of its place.

In order to remove the door from the stove and put it in place again, it is only necessaryl to turn it up sidewisc, so as to bring one of its edges opposite one of the upper angles of the opening or doorway, when it can be easily pushed in or taken ont.

The door and tail-piece are arranged in different planes, in such a manner that, when the door is closed, the center of gravity of the parts will fall inside of a vertical plane passing through the line of support of the door, where the hollow or concave shoulder G rests on the bottom edge of the opening or doorway D, thereby keeping the door up close against the stove. When, on the other hand, the door is opened and turned down toits lowest posi tion, the center of gravity is brought outside of the line of support, and the superior weight of the door keeps it down, the edges of the tail-piece abutting against the inside edgesot' the doorway D and preventing the door falling away from the stove.

Below the grateC is the ash-pit, H, which occupies the whole space between the grate U and the bottom plate I of the stove.

In the ash-pit I place a movable tray or ash-pan, J, of sufficient size to receive the whole contents of the lire box or chamber B. The tray or ash-pan J is removed and replaced through the doorway K.

The oven L is directly behind the firechamber, and is so arranged that its bottom plate is below the level of the grate C, whereby some of the heat which radiates from the lire past the bars of the grate is allowed to act directly upon the front side of said oven.

Below the oven L is a warming-chamber or supplementary oven, M, which occupies ythe space between the main oven and the bottom ofthe stove and between the ash-pit and the yback plate of the stove.

yThe division-plate O, which separates kthe ash-pit from they chamber or oven M, is provided with holes N, through which any cool air which gains access to the chamberM is made to pass out to there by the natural draft of the stove.

The chamber or supplementary oven M is provided with a 'door onfthe same side as the Yusual"door to the main ovenL; and tlrerusual' lues pass under the oven L and behind it, andy connect with the exit-pipe yon the side of the stove.

It will be observed that, by means of my invention, I obtain, in addition to the mainy oven, in which'the highest heat for baking is obtained, a warming-chamber or supplementary oven within the walls of the stove, in

Vwhich chamber I can'place articles that are removed from the main oven, andy which require only amoderate degree of heat to perfect them, while the main oven is continued in use for baking with fullfheat, ythus doing away 'with any necessity for opening the main oven in order to perfect its contents under a 'less degree of heat. f

The chamber M can also be used to bringy articles to a moderate degree of heat, and also to warm the apart-ment when the door of the chamber is left open.

It will yalso beobserved that, by means of the construction and arrangement here shown, a considerable part of the large amount of heat which is found in the ash-pit is saved or utilized by being communicated t0 the chamy chamber Mas I ainaware'that this featfareisVY Y shown in John Vans patent, datedfOctober 6, 1865; neither do I claim the arrangement ot' the Jrire-box, ash-pit, supplemental air-chamber, and oven, as I am aware that this isfnot new. f

Having described my invention in cookingstoves, what I claim as new, and desire to secure by Letters Patent, is

1. The perforated division-plate O, which separates the ash-pit H :fromy the supplement.- ary oven M, substantially as described.

2. The opening D in the wall of the stove at a point below the level of the grate, subf stantially as described. f y

3. The balanced door E, providedwith ay shoulder, G, which forms its point or line of support, and a tail-piece, F, which aids in operating the door, substantially as described y and shown.
